Coupling reactions, suitable for use in organic or aqueous media, are performed by contacting a 1,2,4,5-tetrazine with a dienophile. The dienophile may be covalently bonded to a protein, and the coupling reaction may be performed in biological media such as those containing cells or cell lysates. The reactions may be performed in the presence of primary amines, thiols, acetylenes, azides, phosphines, and products of Staudinger and/or Sharpless-Huisgen reactions Novel 3-substituted cyclopropene compounds and trans-cyclooctenes are exemplary dienophiles for these reactions.
耦合反应,适用于有机或水性介质,通过将1,2,4,5-四唑与二烯丙烯发生反应来进行。二烯丙烯可能与蛋白质共价结合,耦合反应可在含有细胞或细胞裂解产物的生物介质中进行。这些反应可在存在主要胺基、硫醇、乙炔、叠氮化物、膦化合物以及Staudinger和/或Sharpless-Huisgen反应产物的情况下进行。新颖的3-取代环丙烯化合物和反式-环辛烯是这些反应的优秀二烯丙烯。
